Abstract
An intraocular lens including a flexible optic and at least one rigid plate haptic connected to the optic. The at least one rigid plate haptic can include a rigid structure. The at least one rigid plate haptic can be resistant to bending from pressure exerted on a distal end of the at least one haptic by contraction of the ciliary muscle. The intraocular lens can be a non-accommodating IOL having a longitudinal length that is fixed and configured to resist deformation by the action of the ciliary muscle. Various embodiments also include accommodating intraocular lenses.
Claims22
A uniplanar intraocular lens comprising:
- a lens optic;
- a pair of opposing plate haptics flexibly coupled to the lens optic, each haptic comprising:
- a flexible component, and
- a longitudinally rigid frame at least partially embedded in said flexible component and extending beyond the distal edge of said flexible component, the rigidity of said frame being sufficient for the intraocular lens to be capable of resisting deformation by the pressure imposed by a ciliary muscle and by fibrosis without flexing such that the lens optic has the same location along the axis of the eye to maintain a fixed length of the intraocular lens,
- said frame comprising a plurality of rigid loops located along its distal edge,
- wherein said intraocular lens is longitudinally foldable, and
- said lens optic being capable of vaulting posteriorly when said intraocular lens is implanted in an eye.
A monolithic uniplanar intraocular lens comprising:
- a lens optic;
- a pair of opposing plate haptics made from the same material as the lens optic wherein:
- said intraocular lens is longitudinally rigid, the rigidity being sufficient for the intraocular lens to resist deformation by the pressure imposed by the ciliary muscle and by fibrosis without flexing such that the lens optic has a fixed location along the axis of the eye to maintain a fixed length of the intraocular lens,
- said haptic comprising a plurality of rigid loops located along its distal edge, and
- a connecting appendage located between said lens optic and each of said haptics, said connecting appendage being coupled to at least one connecting bar,
- said lens optic being capable of vaulting posteriorly when said intraocular lens is implanted in an eye, and
- said intraocular lens being longitudinally foldable.
